Buying a new furnace and air conditioner can be intimidating. There are lots of options out there and you want to make sure you are getting a good unit at the best price. Our furnace buying guide outlines what you should look for when make your purchase.

Ensure your old unit needs to be replaced

You may be able to service your old unit without replacing it all together. A Trane Comfort Specialist can help you determine if it's time to buy a new unit. Generally, a furnace should last 12 to 18 years with proper maintenance, though some units can last longer. An older unit, however, may run inefficiently and require lots of maintenance, meaning it may be cheaper in the long run to update an older furnace with a newer, more efficient model.

Consider what brand, size and efficiency you want/need

You'll want to choose a reliable brand like Trane for your furnace and air conditioning unit. Also, you'll want to avoid purchasing an oversized unit. If the unit is too big, it can cause uneven temperature problems. Your dealer will be able to measure and inspect your home and recommend the best size. Finally, you'll want to think about an energy efficient furnace and air conditioner. Look at the seasonal energy efficiency ratio (SEER) to help make your decision. While 13 SEER is the minimum, anything about 16 is considered high efficiency. Choosing a high efficiency SEER can potentially cut energy bills in half.

Get multiple estimates

You'll want to get several estimates from Trane dealers. Between the price of the unit and additional options, service contracts and installation costs, you'll want to shop around and compare each bid. Remember that the lowest estimate is not necessarily the best. A higher priced unit may have lower maintenance costs in the long run.

Proper installation is key

A well-trained technician will ensure that your unit is installed properly and that there are no duct leaks when the new equipment is connected to your existing ductwork. Choosing a dealer with the proper training, equipment and knowledge will help ensure your unit is installed correctly.
